New Strategies

This work presents a HPC framework that provides new strategies for resource management and job scheduling, based on executing different applications in shared compute nodes, maximizing platform utilization. The framework includes a scalable monitoring tool that is able to analyze the platform’s compute node utilization. We also introduce an extension of CLARISSE, a middleware for data-staging coordination and control on large-scale HPC platforms that uses the information provided by the monitor in combination with application-level analysis to detect performance degradation in the running applications. This degradation, caused by the fact that the applications share the compute nodes and may compete for their resources, is avoided by means of dynamic application migration. A description of the architecture, as well as a practical evaluation of the proposal, shows significant performance improvements up to 20% in the makespan and 10% in energy consumption compared to a non-optimized execution.

Coordination And Control

Over the centuries and across all societies educational achievement does not improve. The attempt to improve the instructional process has concentrated on instructional technology. But these attempts have overlooked the importance of two other factors: the science that should underlie the instructional technologies and the organization that must operate those technologies. A considerable step forward in handling the problems of instructional effectiveness has been the derivation of instructional technologies based on Skinnerian science. But the instructional technologies based on Skinner's analysis of behavior are promoted as if they were to operate in an organizational vacuum. The division of labor, and its necessary coordination and control, is taken for granted. But in any large scale enterprise, the organization of the division of labor must fit the technology through which that enterprise achieves its mission. Educational technology must tie directly to a pertinent science and to a proper organizational structure. To teach effectively requires an overhaul along three lines: 1) a relevant science that reflects and encapsulates an accurate understanding of behavior; 2) a contingency-based technology of instruction that directly derives its practices upon proper scientific principles; and 3) a suitable organization based on teaching teams that operate the new instructional technology.

Interference in Wireless Sensor Network (WSN) predominantly affects the performance of the WSN. Energy consumption in WSN is one of the greatest concerns in the current generation. This work presents an approach for interference measurement and interference mitigation in point to point network. The nodes are distributed in the network and interference is measured by grouping the nodes in the region of a specific diameter. Hence this approach is scalable and isextended to large scale WSN. Interference is measured in two stages. In the first stage, interference is overcome by allocating time slots to the node stations in Time Division Multiple Access (TDMA) fashion. The node area is split into larger regions and smaller regions. The time slots are allocated to smaller regions in TDMA fashion. A TDMA based time slot allocation algorithm is proposed in this paper to enable reuse of timeslots with minimal interference between smaller regions. In the second stage, the network density and control parameter is introduced to reduce interference in a minor level within smaller node regions. The algorithm issimulated and the system is tested with varying control parameter. The node-level interference and the energy dissipation at nodes are captured by varying the node density of the network. The results indicate that the proposed approach measures the interference and mitigates with minimal energy consumption at nodes and with less overhead transmission.

Today, more than forty countries of the world are engaged in the development of military-purpose robots. A number of unique mobile robots with a wide range of capabilities are already being used by combat and intelligence units of the Armed forces of the developed world countries to conduct battlefield intelligence and support tactical groups. At present, the issue of using the latest information technology in the field of military robotics is thoroughly investigated, and the creation of highly effective information management systems in the land-mobile robotic complexes has acquired a new phase associated with the use of distributed information and sensory systems and consists in the transition from application of separate sensors and devices to the construction of modular information subsystems, which provide the availability of various data sources and complex methods of information processing. The purpose of the article is to investigate the ways to increase the autonomy of the land-mobile robotic complexes using in a non-deterministic conditions of modern combat. Relevance of researches is connected with the necessity of creation of highly effective information and control systems in the perspective robotic means for the needs of Land Forces of Ukraine. The development of the Armed Forces of Ukraine management system based on the criteria adopted by the EU and NATO member states is one of the main directions of increasing the effectiveness of the use of forces (forces), which involves achieving the principles and standards necessary for Ukraine to become a member of the EU and NATO. The inherent features of achieving these criteria will be the transition to a reduction of tasks of the combined-arms units and the large-scale use of high-precision weapons and land remote-controlled robotic devices. According to the views of the leading specialists in the field of robotics, the automation of information subsystems and components of the land-mobile robotic complexes can increase safety, reliability, error-tolerance and the effectiveness of the use of robotic means by standardizing the necessary actions with minimal human intervention, that is, a significant increase in the autonomy of the land-mobile robotic complexes for the needs of Land Forces of Ukraine.

Coordination And Control

This chapter discusses governance dilemmas that are often overlooked in studies that do not encompass the ecology of organization in public governance. The chapter discusses how coordination structures may counteract each other in multilevel systems of government. The ambition of the chapter is twofold: Firstly, a coordination dilemma is theoretically and empirically illustrated by the seeming incompatibility between a more direct (interconnected) and sectorally specialized implementation structure in the multilevel EU administrative system and trends towards strengthening coordination and control within nation states. Secondly, the chapter discusses organizational arrangements that may enable governance systems to live with the coordination dilemma in practice. This coordination dilemma seems to have been largely ignored in the literature on EU network governance and national ‘joined-up government’ respectively.
